[0033] Referring to Figures 1 to 3 , the present utility model provides a large-angle sorting link mechanism, comprising:

[0034] a frame 10;

[0035] a plurality of sorting modules 20, wherein the plurality of sorting modules 20 are all rotatably connected to the frame 10, and the plurality of sorting modules 20 are arranged in a straight line;

[0036] a driving assembly, the driving assembly being in transmission connection with at least one of the plurality of sorting modules 20; and

[0037] a connecting rod 41, the connecting rod 41 comprising at least one arc segment, two ends of the arc segment being respectively rotatably connected to two adjacent sorting modules 20, the driving assembly simultaneously driving the plurality of sorting modules 20 to rotate through the connecting rod 41, and an inner edge of the arc segment avoiding the sorting modules 20.

[0038] The large-angle sorting linkage mechanism in the technical solution of the utility model includes a frame 10, a plurality of sorting modules 20, a driving assembly and a connecting rod 41. The plurality of sorting modules 20 are all rotatably connected to the frame 10, and the plurality of sorting modules 20 are arranged in a straight line. The driving assembly is transmission-connected to at least one of the plurality of sorting modules 20. The connecting rod 41 includes at least one arc segment, and the two ends of the arc segment are rotationally connected to two adjacent sorting modules 20 respectively. The driving assembly drives the plurality of sorting modules 20 to rotate at the same time through the connecting rod 41, and the inner edge of the arc segment avoids the sorting module 20; the driving assembly drives at least one sorting module 20 to rotate, and then the sorting module 20 drives the remaining sorting modules 20 to rotate synchronously through the connecting rod 41. Compared with the method of cooperating with the transmission wheel through the chain and the transmission belt in the prior art, the technical solution of the utility model reduces the use of parts, thereby simplifying the structure of the large-angle sorting linkage mechanism, and thus facilitating the later maintenance of the large-angle sorting linkage mechanism.

[0039] It should be noted that the sorting module 20 includes a diverter drive, a diverter frame and a diverter roller. The diverter roller is rotatably installed on the diverter frame. The diverter drive is installed on the diverter frame and is transmission-connected to the diverter roller. The diverter drive drives the diverter roller to rotate, thereby driving the goods on the diverter roller to move; and the arc-shaped connecting rod 41 drives the sorting module 20 to rotate to control the rotation direction of the goods.

[0040] Furthermore, by setting the connecting rod 41 to be arc-shaped and the inner edge of the arc segment to avoid the setting of the sorting module 20, the connecting rod 41 can drive the sorting module 20 to achieve a larger range of rotation, thereby increasing the flexibility of the large-angle sorting connecting rod mechanism, thereby improving the use scenario of the large-angle sorting connecting rod mechanism.

[0041] Reference Figures 1 to 4 Specifically, the rotation range of the sorting module 20 is 0° to 180°, the arc-shaped connecting rod 41 has a first position, a second position and a third position, the second position is located between the first position and the third position, and the rotation range from the second position to the first position or the third position is 90°, so that the connecting rod 41 can drive the sorting module 20 to achieve a larger rotation, thereby increasing the flexibility of the large-angle sorting connecting rod mechanism, thereby improving the use scenario of the large-angle sorting connecting rod mechanism.

[0042] Preferably, the arc segment is circular. First of all, the circular connecting rod 41 helps to optimize the force transmission path, enabling the force to be transmitted to the target component more smoothly and efficiently; this optimization of force transmission contributes to improving the overall efficiency and response speed of the mechanical system. Secondly, the design of the circular shape can absorb and reduce vibrations and noises generated during mechanical movement to a certain extent; this is because the circular structure has better damping characteristics, which can effectively disperse and weaken the propagation of vibrations and noises. Finally, the circular connecting rod 41 can enhance the stability of the overall structure, because the circular shape can provide better support and balance effects, reducing stress concentration and deformation of the structural components during movement. Of course, in other embodiments, the arc segment can also be elliptical.

[0043] Furthermore, the radian of multiple arc segments is the same, which simplifies the structure of the connecting rod 41, facilitates the processing of the connecting rod 41, and further reduces the production and manufacturing cost of the connecting rod 41.

[0044] Specifically, two adjacent arc segments are arc-transitioned. It can be understood that the design of arc-transition can enhance the overall structural strength of the connecting rod 41, because the arc structure can better resist bending and torsional forces, so it can increase the stability and reliability of the connecting rod 41 under complex working conditions; at the same time, the arc-transition can disperse the stress generated during the operation of the connecting rod 41, reducing the phenomenon of stress concentration, thereby improving the durability and service life of the connecting rod 41.

[0045] In an embodiment, the connecting rod 41 is integrally formed. The processing method of integral setting is stable, reliable, and has strong stability, and the processing cost is relatively low, thereby increasing the structural strength and service life of the connecting rod 41 and reducing the production and manufacturing cost of the connecting rod 41.

[0046] Refer to Figures 5 to 7 , in an embodiment, a plurality of second connection holes 411 are provided on the connecting rod 41, a first connection hole 22 is provided on a sorting module 20, one second connection hole 411 corresponds to one first connection hole 22, and the second connection hole 411 and the first connection hole 22 cooperate with a connecting member to rotatably connect the sorting module 20 and the connecting rod 41.

[0047] Specifically, the connecting member includes a connecting pin 42. One end of the connecting pin 42 is provided with a limiting portion 422, and the other end of the connecting pin 42 is provided with a jack 421a. The limiting portion 422 is used to abut against the lower surface of the connecting rod 41. The jack 421a is formed by penetrating the side wall of the connecting pin 42. The connecting pin 42 sequentially passes through the second connecting hole 411 and the first connecting hole 22. The large-angle sorting connecting rod mechanism further includes a limiting member 43, and the limiting member 43 is inserted into the jack 421a. An elastic member 44 is sleeved on the connecting pin 42. One end of the elastic member 44 abuts against the lug 21, and the other end abuts against the limiting member 43.

[0048] Further, the connecting pin 42 can be welded and arranged in the second connecting hole 411, or can be arranged in the second connecting hole 411 by screwing or clamping, or can be directly arranged by passing through the second connecting hole 411, and no specific limitation is made thereto. The connecting pin 42 arranged in the second connecting hole 411 passes through the first connecting hole 22 and has a clearance fit with the first connecting hole 22, so that a plurality of sorting modules 20 are connected together through the connecting rod 41 structure, facilitating the synchronous rotation of the plurality of sorting modules 20.

[0049] Specifically, the connecting pin 42 includes a main body portion 421 and a limiting portion 422. The limiting portion 422 is arranged at the end of the main body portion 421. The main body portion 421 is arranged in a cylindrical shape, and the limiting portion 422 is arranged in a circular disc shape. And a jack 421a is opened at one end of the main body portion 421 away from the limiting portion 422. When the connecting pin 42 realizes the clearance fit with the first connecting hole 22, it sequentially passes through the second connecting hole 411 and the first connecting hole 22, and the limiting portion 422 is used to abut against the lower surface of the connecting rod 41, and a limiting member 43 is inserted into the jack 421a to prevent the connecting pin 42 from coming out of the first connecting hole 22 and the second connecting hole 411.

[0050] If the interval space between the connecting rod 41 and the sorting module 20 is small, then the possibility of interference between the connecting rod 41 and the components of the sorting module 20 during rotation is relatively large, which makes the space that needs to be avoided between the connecting rod 41 and the sorting module 20 large, thereby increasing the size of the connecting rod 41 and reducing the stability and reliability of the connecting rod 41 during operation. Therefore, in an embodiment, a lug 21 is provided on the sorting module 20, and the lug 21 protrudes from the sorting module 20, and the first connecting hole 22 is arranged on the lug 21. By providing the lug 21, the interval space between the connecting rod 41 and the sorting module 20 is increased, thereby reducing the possibility of interference with the components of the sorting module 20 during rotation, further making the space that needs to be avoided between the connecting rod 41 and the sorting module 20 small, further facilitating the miniaturization of the connecting rod 41, and improving the stability and reliability of the connecting rod 41 during operation.

[0051] Further, the lug 21 is arranged to gradually decrease in the direction away from the sorting module 20, and the first connection hole 22 is arranged at one end of the lug 21 away from the sorting module 20. By gradually reducing the lug 21, the contact surface between the lug 21 and the connecting rod 41 is reduced, thereby reducing the friction between the lug 21 and the connecting rod 41, and further improving the transmission efficiency of the connecting rod 41; at the same time, the noise generated during the movement of the lug 21 and the connecting rod 41 is also reduced, thereby improving the user experience.

[0052] Further, an elastic member 44 is sleeved on the connecting pin 42. One end of the elastic member 44 abuts against the lug 21, and the other end abuts against the limiting member 43, so as to provide an upward acting force for the connecting pin 42 to ensure that the connecting pin 42 inserted into the second connection hole 411 and the first connection hole 22 will not fall down. At the same time, the limiting portion 422 also abuts against the lower surface of the connecting rod 41, applying an upward acting force to the connecting rod 41 to prevent the longer connecting rod 41 from deflecting downward.

[0053] It should be noted that, in this embodiment, the connecting pin 42 connects the connecting rod 41 structure and the sorting module 20 by sequentially passing through the second connection hole 411 and the first connection hole 22. The connecting pin 42 does not need to be connected to the connecting rod 41 by screwing, welding, clamping or other connection methods. The direct passing-through method is simple and convenient to operate, and can also apply an upward acting force to the connecting rod 41 to prevent the longer connecting rod 41 from deflecting downward.

[0054] Furthermore, since the first connection hole 22 is formed on the lug 21 and the lug 21 is usually thin, the wall height of the first connection hole 22 is short. During the movement of the connecting rod 41 structure driving the sorting module 20 to rotate, the contact area between the connecting pin 42 and the first connection hole 22 is small, which easily causes the sorting module 20 to swing up and down during rotation, affecting the rotation effect and also affecting the service life of the lug 21. Therefore, to solve the above problems, the large-angle sorting connecting rod mechanism further includes a connecting sleeve 45. The connecting sleeve 45 is arranged in the first connection hole 22, and the connecting sleeve 45 has a fitting hole for the connecting pin 42 to pass through. The connecting pin 42 is rotationally fitted with the connecting sleeve 45, and the connecting pin 42 and the fitting hole are in clearance fit. One end of the elastic member 44 abuts against the connecting sleeve 45, and the other end abuts against the limiting member 43.

[0055] In one embodiment, the driving assembly includes a driving motor 31, a driving wheel 32 and a driven wheel 33. The driving motor 31 is installed on the frame 10. The driving wheel 32 is in transmission connection with the output shaft of the driving motor 31. The driving wheel 32 meshes with the driven wheel 33. The driven wheel 33 is fixedly installed on one of the plurality of sorting modules 20. The meshing transmission between the driving wheel 32 and the driven wheel 33 has high efficiency and is stable and reliable during operation. Of course, in other embodiments, the driving assembly may further include a transmission belt. At this time, the driving wheel 32 and the driven wheel 33 are roller wheels, and both the driving wheel 32 and the driven wheel 33 are rotatably installed on the frame 10. The transmission belt is sleeved on the driving wheel 32 and the driven wheel 33, and the driving motor 31 drives the driven wheel 33 to rotate through the cooperation of the driving wheel 32 and the transmission belt.

[0056] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
